VANCOUVER - Losing sleep over their stunning loss last week in Montreal was inevitable for the B.C. Lions.

But after having a few days to digest the heartbreaking defeat to an injury-depleted Alouettes team, the Leos were back at it Monday at their Surrey practice facility, trying to focus on this Friday's home showdown against the Hamilton Tiger-Cats.

"It takes about 24 hours to flush it out of your system," quarterback Travis Lulay said of the 39-38 loss — which saw the Als kick a last-second field goal. "It's business as usual as to what we could have done differently. Obviously in a loss, especially in a loss by one point, you go through the plays and say this play or this play could have come out different, but you can't dwell on those."

Still, the disheartening result in a game where the Leos failed time and time again to close out is tough to swallow.

For the players, they claim they've put it behind them. But having forced six turnovers, scored a special teams touchdown and facing a third-string quarterback, B.C. knew they should have come away with a road win.

"Everybody is tremendously disappointed," coach Mike Benevides said. "We've got to grow from that. There's a lot of anger … and that's a good thing. Our expectations are high and we have to be better and make sure that what happened doesn't happen again."

That means dissecting and learning from it. The key theme Monday from the players on where to improve was limiting the mistakes and making more big plays — especially offensively.

The team rushed for just 54 yards while failing to set a tone early with way too many two-and-outs. The defence, meanwhile, gave up an uncanny amount of long bombs to rookie pivot Tanner Marsh, including the 57-yard, Hail Mary pass to set up the winning field goal.

"You walk away from the game and still can't believe what happened," linebacker Adam Bighill said. "You can't just hop on a time capsule and go back to Thursday night and change it. There's no sense in dwelling on it and it's all about moving forward."
